Abstract

The present invention relates to an exhaust-gas turbocharger (1) having a compressor housing (2); having a turbine housing (3); and having a bearing housing (4) which has a compressor-side flange (5) and which has a turbine-housing-side flange (6), wherein the turbine-housing-side flange (6) is produced from a material which corresponds in terms of its mechanical and thermal properties to the material of the turbine housing (2).

Description

EXHAUST-GAS TURBOCHARGER DESCRIPTION The invention relates to an exhaust-gas turbocharger as per the preamble of claim
1.
An exhaust-gas turbocharger of said type has not only a compressor with a compressor housing, but also a turbine with a turbine housing which is fastened to a bearing housing via a bearing-housing-side flange. Here, an already known generic exhaust-gas turbocharger has a bearing housing produced from a material as a cast part.
Said cast material may be composed of a pearlitic micro structure which, when heated to over 450°C, begins to lose its structure because the pearlite breaks down into its constituent parts. Here, firstly, a change in volume of the material takes place and, secondly, the bearing housing loses its hardness (HB). Said loss of hardness may be so drastic that, specifically in conjunction with dendritic formation of the matrix of the material, significant crack formations may occur.
The bearing housing material is subjected to a very high temperature in particular at the contact surface or the fit with respect to the turbine housing, and is additionally subjected to mechanical loading by the clamping forces of the connecting elements. In conjunction with said loadings, the vibrations resulting from the engine running during use of the exhaust-gas turbocharger, and the different coefficients of expansion of the bearing housing and the turbine housing, said crack formation occurs in the bearing- housing-side flange, which results in a direct leakage of exhaust gas at the connecting point between the bearing housing and the turbine housing.
It is therefore an object of the present invention to provide an exhaust-gas turbocharger of the type specified in the preamble of claim 1, which exhaust-gas turbocharger makes it possible to minimize or eliminate the above-explained problems of the generic turbocharger.
Said object is achieved by means of the features of claim 1.
It is achieved by means of said features that the highly loaded contact region between the turbine housing and bearing housing is formed by a material which can be subjected to greater loading.
Here, the turbine-side bearing housing flange may be replaced by a separate flange composed of a higher-grade material in relation to the known solution. To realize a reliable connection of the bearing housing to the turbine housing with regard to strength and sealing action at high temperatures, the material for the fiange to be mounted separately on the bearing housing is matched in terms of its properties to those of the turbine housing.
Depending on the turbine housing material used, the turbine-housing-side flange may be produced from a high-temperature-resistant ferritic material (for example X22XCrMoV 12-1 (1.4923)) or from an austenitic cast steel (for example GX40MeCrSiNb38-18 (1.4849)).
The subclaims relate to advantageous refinements of the invention.
The connection of the separate turbine-housing-side flange to the bearing housing may be realized by means of screw connections, shrink-fit connections, welded connections, adhesive connections, soldered connections, composite casting or a combination of the above connection types.
The machining of the bearing housing can preferably be carried out in the conventional way after the fixing of the separate flange to the bearing housing.
Further details, features and advantages of the invention will emerge from the following description of exemplary embodiments on the basis of the drawing, in which:
figure 1 shows a sectional perspective illustration of an exhaust-gas turbocharger according to the invention,
figure 2 shows a plan view of the bearing housing of the exhaust-gas turbocharger as viewed from the turbine,
figure 3 shows a section through the bearing housing along the line A-A in figure
2,
figure 4 shows a perspective illustration of a further embodiment of the bearing housing according to the invention,
figure 5 shows a sectional illustration, corresponding to figure 3, of the bearing housing as per figure 4,
figure 6 shows a partial view of the bearing housing as per figure 4,
figure 7 shows an illustration, corresponding to figure 4, of a further embodiment of the bearing housing according to the invention,
figure 8 shows an illustration, corresponding to figure 5, of the bearing housing as per figure 7,
figure 9 shows an illustration, corresponding to figure 6, of the bearing housing as per figure 7,
figure 10 shows an illustration, corresponding to figure 7, of a further embodiment of the bearing housing according to the invention, and
figure 11 shows an illustration, corresponding to figure 8, of the bearing housing as per figure 10.
Figure 1 illustrates an exhaust-gas turbocharger 1 according to the invention which has a compressor 7 and a compressor housing 2.
The exhaust-gas turbocharger 1 also has a turbine 8 with a turbine housing 3 and has a bearing housing 4 which is connected via a compressor-side flange 5 to the compressor 7 and via a turbine-housing-side flange 6 to the turbine 8 or the turbine housing 3.
The design of the turbine-housing-side flange 6 will be explained in detail below on the basis of figures 2 to 11. The exhaust-gas turbocharger illustrated in figure 1 self- evidently also has all the other components of such turbochargers, said components however not being described in detail because they are not required for explaining the principles of the present invention.
Figures 2 and 3 illustrate a first embodiment of the bearing housing 6 according to the invention of the exhaust-gas turbocharger 1.
The view in figure 2 is a view from the direction of the turbine 8, and shows the bearing housing 4 with its turbine-housing-side flange 6, wherein, owing to the selected illustration, it is possible to see an arrangement 9 composed of a bush, a lever and a pin, and also two dowel pins 10 and 11.
Figure 3 shows that the turbine-housing-side flange 6, which is formed as a separate component, is formed as a steel flange which can be either screwed or welded to the bearing housing 4. The reference numeral 14 symbolically indicates one of the possible weld points of a multiplicity of weld points.
Figures 4 to 6 illustrate a further embodiment of the bearing housing 4 according to the invention, wherein all of the features which correspond to figures 2 and 3 are denoted by the same reference numerals.
In said design variant, the flange 6 is cast integrally with the bearing housing 4, wherein figure 5 shows that the connection is realized by means of a suitable shaping 17.
Figures 4 and 6 furthermore show two recesses 15 and 16 which, in said embodiment, are situated entirely within the surface of the flange 6.
Figures 7 to 9 illustrate a further design variant of an integrally cast flange 6, wherein figure 8 again shows the form fit 17. Said embodiment otherwise corresponds to the embodiment as per figures 4 to 6, aside from the fact that figure 9 shows that the recesses 15 and 16 are situated partially in the material of the flange 6 and partially in the material of the bearing housing 4.
Figures 10 and 11 show a variant which substantially corresponds to the embodiment as per figures 2 and 3 and in which the flange 6 is screwed to the bearing housing 4 by means of an internal/external thread 13. The recesses 15 and 16 as per figure 9 serve, together with the pressed-in bush 9 or the pressed-in pin 11 (shown in figure 2), as a rotation prevention means.
All of the above-explained design variants of the bearing housing 4 according to the invention have in common the fact that the flange 6 is matched in terms of its material properties to the material of the turbine housing 3, such that the problems explained in the introduction, in particular with regard to undesired crack formation in the region of the contact point between the bearing housing 4 and the turbine housing 3, can be eliminated.
In addition to the above written disclosure of the invention, reference is hereby made explicitly to the diagrammatic illustration thereof in figures 1 to 11.
